I Fig. 3 is an operating valve of slightly modified construction in section on line 3-3 of Fig. 4-

Fig. 4 is a cross section of the operating valve in Fig. 3 on line 4-4.

In Fig. 1, 5 designates the driving shaft to which the rotating wheel 6 is keyed as indicated 'at 7. The-rotating wheel is proof recesses .9. -Valves or gates 10 are slidngly mounted in the recesses 9 of the rotatmg wheel 6. The housing 11 is suitably stored and compressed on the transmitting formed to leave a space or channel 12beshaft and used as driving means on the power receiving shaft.

Another object is to provide a motor on the driving shaft by which a liquid is stored and compressed to be used on the power receiving shaft.

Another object is to provide a motor on the power receiving shaft which can be operated by a liquid received from the liquid storing and compressing motor on the power transmitting shaft.

Another object is to provide a device which can be used as a, or in place of the difierential gearing in automobiles or in similar places. Another object is to provide a device which can be used as a pump for compressing a liquid and transmitting the liquid to a power receiving device or other suitable place.

Another object is to provide a device which can be used as a pump and also as a rotary motor, of the rotary type.

Another object is to provide a device of the character indicated above to take the place of change-speed gears in automobiles.

Another object is to provide a device of the'character indicated above to take. at the same time the place of brakes in automobiles.

' which' Figure 1 is a side elevation of my device,

partly in midsectiom Fig. 2 is a section of the direction changts jiFng valverof-the device on line 2-2 of ig.1. A

ma mng section of the rotating wheel is' closely engaging with the housing as illustrated between the numerals 13 and 14. The gates 10 are provided with extension ends 15, projecting sidewise from the gates into suitably formed grooves 16, provided in thesides of the housing. Preferablygsuch grooves 16 are in the opposite s'ides'of the housing, equally formed, facing the inside of the housing, so as to guide the gates 10 by their extension ends 15 to slidingly engage with the larger partof the housing, while withdrawing the gates to pass the narrower part of the housing between the numerals 13 and 14 in such withdrawn osition within the recess of the rotating w eel, as will easily-be understood from the illustration. The narrower part of the housing between the numerals 13 and 14 forms the checking block 17, which, though shown as solid wlth the housing, may preferably be an independent member suitablyisecured to the inside of the housin on line 18, indicated in dotted lines. This 0 ecking block is provided with deflecting and guiding curves vided with aflange 8 and a suitable number 19 and 20, checking and guiding the liquid I from the channel 12 in the upper part of the housing into the outlet 21 and from the intake 22 into the lower part of the channel 12. Making the checking block an independent part secured to the housing allows an absolutely circular facing to the inside of the housing.

On the shaft 23 is mounted a similar rotating Wheel with valves or gates inclosed by a similar housing as described above.

The pressure, produced by the motor described above and illustrated to the left in Fig. 1, is used as the driving power for the motor shown in side elevation to the right in the same figure.

. 65 outlet being directed through the connect- The direction changing valve 24 between thetwo motors is illustrated in crossgsection inFig. 2. The rotating center body is, provided with the two curved conduits 25 and 26, the cross conduit 27 and the longitudinal conduit 28; the curved conduits 25 and 26 being on the same level, the

cross conduit above the curved conduits, and the longitudinal conduit below the curved conduits. The connecting conduits 29, 30, 31 and 32 are provided with upwardly or downwardly leading communicating conduits 33, the-conduits and 32 preferably withthe upwardly leading communicating conduits, while the conduits 29'and 31 are provided with the downwardly leading communicating conduits, though it may be in the opposite manner.

In the position illustrated in Fig. 1, when rotating the shaft 5 with the rotating wheel secured thereto, the liquid is naturally sucked or drawn in from the intake 22 through the channel 12 and pressed out through the outlet 21, passing through the curved conduit 25 into the motoron the shaft 23, transmitting the rotating motion of the motor on the shaft 5 to'the motor on thefshaft '23, as will easily be understood.-

The liquid passing out of the motor on the shaft 23 passes through the curved conduit 26 back into the motor on the shaft 5.

When using this device as a pump, the conduit 22' will naturally be used to draw the liquid and the conduit 21 to deliver the 7 liquid, and no second motor is necessary in 1 such case.

When using this device on automobiles or similar devices, the motor on the shaft 23 is coupled or connected with one or more of the wheels'of such vehicles or devices.

Putting one motor on each of the rear wheels, makes it possible to eliminate the, differential gearing in such vehicles, the

motor on-e ach wheel being capable of producing the same effect as'obtained'by the differential gearing, as will easily'be understood. Having one motor on eachof the driving wheels eliminates also the slipping 'of one wheel, very common with'diiferentials, this advantage being especially important in trucking.

If the shaft 5, iscapable of reversing, the whole system and the direction of the shaft 23 can naturally be reversed, if, however, a reversing of shaft 5 is not possible, the reversing of shaft 23 is accomplished through the several conduits in the valve 24. Turn- -ing the valve 24 to'a suitable distance to bring the conduit 28 to aline with the connecting conduits 29 and 31, and the conduit 27 to aline with the connecting conduits 30 and. 32, naturally connects the outlet 21- to" the motor on shaft 23 in the opposite manner as described above, the pressure from the ing conduit 29, through the longitudinal conduit-28 in the valve 24, through the con-.

necting conduit 31 into the lower part of the motor on. the shaft 23, while the pressure as described above entered the motor on shaft 23 in the upper part.

If the motor on shaft 23 is to be stopped .while the motor on shaft 5, is running, it

naturally requires that the space 34, see Fig.2, between the conduits should be at least larger than the width of such con-- duits providing a neutral position in this valve, which can easily be had, as-will easily be understood.

Running the motor on shaft 5 at normal speed, the motor on shaft 23' is controlled by the operating valve 35, by allowing more or less of the pressure produced in the motor on shaft 5 to circulate back to that motor through-the operating valve 35. The motor on shaft 23 requiring power while the pressure canfreely circulate through the operating valve 35 when open naturally causes a stopping of the motor on shaft 23 when the operating valve is open. v

If the motor on shaft 5 is directly coupled with the driving: motor of an automobile such idle circulation is of course necessary, and astarting of the motor on shaft 23 is simply obtained by gradually closing the op erating valve 35, therebyvery evenly and gradually causing more. and more of the 23, as will easily be understood.

Having started the driving force of an automobile, gas-engine, electric motor, or any other suitable motor, and having fully .pre'ssureto pass over'to the motor on shaft opened the operating 'valve, the direction I changing valve 24 is set in the desiredposition and then the operating valve 35 graduthe motor on shaft 23 as desired.

For coasting when the motor on shaft-5 draw new liquid in at\ the opposite conduit this being made impossible by the shutting off of the circulation through the brake valve36. r v

' A modified form of operating valve is illus trated in Figs. 3 and 4. thechecking block 17 being enlarged and this enlarged block forming the operating valve 37. For the operating valve 37 a suitablecompartment 38 105 ally closed as described above for starting' erating valve is sliding'ly --mounted-radially to the rotating wheel 6. T he curved face '39 is the same as in the checking block 17 beiween the numerals 13'and 14, slidingly engaging with the periphery of the wheel 6' i when the operating valve 37 is in its closed position. ,Two small racks 40 are provided-- on the operating valve 37, with which two;

smalI-pini'ons 4L1 engage. The pinions being on the same shaft 42, in turning this small shaft 42 andtherebythe pinions 41,

the operating valve block 37 "is easily shiftedtoward the rotating wheel 6 or in the opposite dii'ection. Inthis modified form no outside overflow with operating valve 35 is necessarythe liquid being able to circulate within the housing past the curved face'when theoperati-ng valve block is withdrawn-into the .compartment38, A

. A device stood that slight changes of details can be made without departing from the invention or the principle of the invention.

Having thus described my invention, I claim:
